Group horses have been part of the breed for a long time now.  Over the years they unfortunately haven’t had much significant meaning beyond being able to be leased for events or being bred to.  We’d often see Group Horses retire before getting any real love from the community, so we’ve been looking at various ways to make Group Horses a little more special.  
Over the past few months we’ve slowly been adding in personalities as well as regional transformations for Group Horses.  We’ve also been picking Group Horses to be part of the official lore of Equinox and Solstice events which has been a fun way of integrating them into the breed a bit further.  
Moving forward we’re going to be fleshing group horses and their general lore out a bit more.  We plan on adding magics to them as well.  These will be magics that the Group Horses have access to while in service as Group Horses, and then upon retirement most of the magic will be returned along with access to the regional transformation they had. 
Once rehomed, Group Horses will be eligible to retain one or two of the magics.  Returned magics will need to be unlocked again by the new owner via chime updates etc however.  If the new owner opts to choose different magics or regional transformation, that is perfectly acceptable.  This is essentially our way of giving the new owners options to decide what path their retired Group Horse takes, since Phoenix Touch isn’t available to them.  

Expect to see a new way for rehoming retired Group Horses in the near future as well.
